VAPORIZER FOR HYDROCARBON-VAPOR LAMPS AND STOVES.

Patented July 2, 1912.

Application filed July 25, 1911. Serial No. 640,532.

This invention relates to the vaporizing devices used in that class of oil lamps and stoves in which oil or other light hydrocarbon or spirit, in course of supply to the burner, is vaporized, to be afterward mixed with air and subsequently consumed. It has been specially devised in order to provide an improved vaporizer whereby the oil will be more efficiently vaporized, the discharge of the vapor may be regulated, and the discharge nozzle or nipple may be readily cleared or freed of carbonaceous or other deposits therein.

Although this improved vaporizer is particularly adapted for use with a lamp in which a bent mixing or Bunsen tube conveys the discharge vapor through a hood to a depending mantle, it is equally well adapt-- able to other vapor lamps and also to stoves and heaters.

According to this invention the improved vaporizer for hydro-carbon vapor lamps and stoves comprises an oil or spirit supply tube adapted to be connected at one end to a reservoir and having in the other end a plug containing a needle valve and terminating in a discharge nozzle or nipple. The central passage of the needle valve communicates with a guide tube within the supply tube and which guide tube carries the regulating rod of the needle. The needle carries in addition a clearing point. The needle valve plug has a side passage allowing communication with the supply tube of one side of a transverse division in a superheater tube positioned above or near the point of ignition and having the other side of said division in communication with a part leading to the central passage of said plug which passage is in communication with the discharge nipple. But in order that a practical application of the invention may be readily understood the same will now be described with reference to the drawings accompanying and forming part of this complete specification in which Figure 1 is a vertical central sectional elevatio-n showing in dotted lines an arrangement of hood, Bunsen tube and mantle. Fig. 2 a plan thereof and Figs. 3 and 4 sectional views on the lines 8. 3 and 4. 4 respectively in Figs. 2 and 3.

The supply tube 5 with sc'rewed end 6 for connecting to a reservoir has in the other end a plug 7 with central passage 8 terminating in discharge nozzle or nipple 9 with orifice 10. This central passage 8 is .connected to the guide tube 11 within the supply tube 5 which tube 11 is connected to a tubular screwed thimble 12 protruding through an angular portion 13 of said supply tube 5 and carrying a winged gland nut 14 with packing 15 therein through which passes the regulating rod 16 with milled head 17 of the needle 18 which latter regulates the supply of vapor through the passage of the nozzle to the discharge orifice 10 and has a clearing point 19 to clear deposits or obstructions from said orifice 10. This plug 7 has passage 20 allowing communication with the supply tube 5 of one end of super-heating tube 21. The other end of this tube 21 is in communication with the port 22 leading to the central passage 8 of the needle plug 7 and to the passage in the nipple 9 terminating in discharge orifice 10.

In use the oil or spirits being supplied under pressure from a reservoir as ordinaril to the supply tube 5 it passes up same and ecoming vaporized in the upper portion thereof passes through the passage 20 into the tube 21 where it is superheated and then passes through port 22 into passage 8 and discharges through the needle valve orifice 10.

The rod 16 may be operated by its head 17 so that the clearing point 19 will dislodge any deposit in the needle valve orifice 10 and further so that the needle will control the flow of vapor through passage of the nipple and regulate the discharge from the valve orifice 10. To effectively close the. guide tube 11 and to set the rod 16 in desired position the gland 14 is tightened on the thimble 12 so thatthe packing 15 on the end thereof will make a tight joint and jam said rod 16 in set position.

Having now fully described and ascertained my said invention and the manner in which it is to be performed I declare that what I claim is 1. In a vaporizer, in combination, a supply tube, a discharge nozzle, a superheater tube having one of its ends communicating with said supply tube and its other end communicating with said discharge nozzle, and an adjustable regulating rod extending through said supply tube and provided with a needle cooperatively associated with said discharge nozzle for regulating the flow of vapor therethrough.

2. In a vaporizer, in combination, a supply tube provided with a perforated plug in one end thereof, a superheating tube supported by said supply tube, said plug being provided with a passage communicating with one end of said superheating tube, said plug being provlded with a port communicating with the other end of said superheat- Copies of this patent may be obtained for ing tube and with the perforation in said plug, a nozzle communicating with the perforation in said plug, a guide tube extending within said supply tube and connected with the perforation in said plug, and an adjustable regulating rod positioned within said guide tube and provided with a needle cooperatively associated with said nozzle to regulate the flow of vaportherethrough.

In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses.
